Title: Apparatus for cutting film strips
IPC: G03D15/04
Filed: 1971-09-30
Abstract: 1363447 Automatic electric control of printing AGFA-GEVAERT AG 30 Sept 1971 [30 Sept 1970] 45612/71 Heading G3N A film-strip 12 carries notches 12a, indicating printable originals, in the middle of a frame and notches 12d, at joints 12c, which prevent the spread of adhesive. The strip is moved by a D. C. motor 17 controlled in response to the output of a pulse generator 18. The strip moves over photo-electric scanning devices of which device 13a indicates a notch 12a, devices 13a, 13b both emit a pulse when notches 12d pass and a device 13c scans film perforations and is used when the strip is of the kind where the relationship between perforations and frames is fixed. The length of film fed is determined by a perforated disc, coupled to the film surface, associated with a light-emitting diode 22 and a photo-transistor 24 the pulses from which are fed through a Schmitt trigger to a counter 25. The counter provides a control signal on completion of four lengths, comprising an approximate strip length 28, a frame length 29, a length 30 equal to distance from notch 12a to the cutting position and a length 31, indicative of a braking distance. When there is no notch 12a within the length 30, the film transport is stopped after an over-run, and where the absence of a notch indicates that the frame is unprintable, by an auxiliary counter 46. The identification of a splicing point causes, after a delay, a signal on an output 26b which is applied to gate 49 to bring about a speed reduction and stop with a simultaneous cutting command. Completion of each of lengths 28, 29, 30, 31, through flip-flop stores 32, 34, 50, 51, sequentially command speed reduction and stop, by modifying the reference voltage in a retro-active motor controller 36 and the initiation of a cutting operation by a knife 14 through a flip-flop store 64.

Filed: 1972-10-04
Abstract: 1357674 Time switches DIEHL 4 Oct 1972 [4 Nov 1971] 45648/72 Heading H1N A time switch, for a cooker oven for example, having an audible signalling means which is energized by closure of secondary contacts when the main contacts are opened is provided with automatic means to open the secondary contacts after a predetermined time. A motor 7 is coupled via a clutch 6 and gear 4 to gearwheel 5 having two gaps 53 and 55 in its teeth, leaving a toothed segment 54 therebetween. Wheel 5 is rigid with two cams 51 and 52 having respective follower arms 8 and 9 for actuating main power contacts and audible signalling contacts (not shown) respectively. The wheel 5 and cams 51, 52 may be an integral moulding. A time-interval indicating disc 3 is rigidly coupled to the wheel 5 and may be rotated manually by knob 1 to set a cooking time. This lifts the arm 8 to switch the power on and arm 9 to switch a buzzer, for example, off. Motor 7 then rotates wheel 5 back to its zero position where arm 8 drops into recess 512 to switch power off and arm 9 drops into recess 522 to switch the buzzer on. The toothless gap 53 in wheel 5 allows arms 8 and 9 to fall suddenly down the switching ramps 511 and 521, thereby moving the segment 54 into engagement with gear 4 and continuing the drive to wheel 5 until after an interval arm 9 is lifted up to locate in notch 524 and switch the buzzer off, while arm 8 maintains its "off" position, and gear 4 idles in the toothless gap 55. By slightly turning knob 1 the arm 9 may now be moved on to portion 525 while arm 8 locates in notch 514 (both switches being maintained "off") and indicator disc 3 reveals an "OFF" marking under a viewing window (not shown).

Title: Unstacking machine
IPC: B65G59/02
Filed: 1963-12-03
Abstract: 988,990. Unstacking from pallets. G. E. VON GAL. Dec. 3, 1963, No. 47612/63. Heading B8C. Pallets, each of which carries a stack of crated bottles, six crates to a layer, are fed to a machine which automatically raises each pallet to a position where slide plates 100, 100<SP>1</SP> enter below the top layer of the stack and rakes 165, 165<SP>1</SP> urge the layer from the plates on to driven discharge rollers, Fig. 4 (not shown), the unloading operation continuing until the empty pallet is lowered and stacked in a magazine. Loaded pallets are fed towards the machine on an inclined rollerway, Fig. 2 (not shown), leading to a section of endless belt conveyer, the leading pallet being delivered to a second endless conveyer 28 where it trips a lever to stop the section of endless belt and thereby hold up subsequent pallets. When in position to be lifted by a frame 70, 71, 82, 83 the loaded pallet trips a switch to raise the frame by means of motor-driven chains 72. One of two pre-set switches, Fig. 6 (not shown), stops the lift, the switch being selected according to the height of bottles carried, and the slide plates 100, 100<SP>1</SP> close pneumatically. Tines 118, 119 on the side plates pass between the bottle necks of the second layer from the top, the upper parts of the tines engaging the outer edges of the top layer of crates, compacting and raising them to bring the plates 100, 100<SP>1</SP> beneath them. When closed, the side plates actuate switches to start a ram mechanism which, by means of the rakes 165, 165<SP>1</SP>, urges the crates two at a time, into the control of driven rollers 192, 192<SP>1</SP> on to the discharge rollers. Further switches cause the rakes and side plates to return. The lowermost layer is removed from the pallet without the use of the side plates 100, 100<SP>1</SP> and tines, the pallet touching a switch controlling the drive to the rakes 165, 165<SP>1</SP>. The lift discharges the empty pallet, when lowered, to chains 59 carrying it to a magazine where it is automatically raised on skids 208a, 208b, Fig. 7. The rising pallet urges rocker arms 221a-221d outwards until it is held by fingers 220, 220<SP>1</SP>. When the magazine is filled, the uppermost pallet operates a switch to prevent the feed of further pallets either to the lift or to the magazine. U.S.A. Specification 3,056,513 is referred to.
